Designed by AIKON Electronics, the SEFM 30A Blheli_S  ESC is designed to give silky smooth feeling to the powerful arsenal of Blheli ESCs. Utilizing hardware PWM with the one of a kind EFM BusyBee 48MHz MCU power, SEFM30A coupled with Blheli_S firmware specifically written by Steffen for this ESC has truly bring the open source firmware to a whole new level.

The first offering of a new generation of BLHeli ESCs.  Designed to bring high performance through hardware PWM and the Silabs Busybee line of microprocessors.  Stated benefits are more throttle resolution, smoother response, higher RPM ability and automatic detection of OneShot 125, OneShot 42 and Multishot protocols.
